Appiication fiied November 24, 1908. seriai No. 464,273,

To all 'whom 'it 'ma/y concern:

Be it known that I, WARNIE A. FUscH, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented a new and useful Re-l inforced-Concrete Slab, of which the following is a specification.

The object of the present invention is to a fiooring for bridges and buildings.

Reinforced concrete is being used for bridge floors, and the usual-systein of building the same is by using a metal arcli the ends of which rest on the lower fiaiiges of the joists. The wet concrete is filled in above the arches to lthe desired height. ThisI method of constructing the fiooi'ing is ob-- jectionable because it cannot be employed during freezing weather with satisfactoi'y results. Another objection is that after thel concrete fioor has been completed, it is necessary that it should be seasoned before it can .be used for travel,I thus causing a delay to travel after the floor has been completed. My invention consists of a portable slab of the building site and placed in position for imiiiediate use, regardless of' the Weather,

The invention also -has for its object to Another object of the invention is to provide a slab of the kind stated which is strong and durable, and which 'can be easily and' In Figure 1 of the accompanying drawings is shown inperspective, a poi'tion of a bridge fioor, showing the application of the invention.. Fic'. 2 isV a perspective view4 of the frame of the slab, together with the reinforcing members. Fig. 3jis a plan view partly broken away showing the corner fastening Fig. 4 `1s a transverse section of the slab. Fig. -5 is a plan lview of a modified`form of corner fittings.

. Referring more-particularly to'the draw- The frame is rectangul ar in shape, and may be of any size desired. In the construction of the frame I employ channel beams,, -the clearly 'shown in Fi 4 of the drawings.

. The frame 5 is ed with concrete 7 which is embedded a reinforcing member 8 l Fig. 2. Tongues or hooks 9 are punched in the Web of the channel frame at the sides and ends thereof, to Which tongues or hooks the ends of the wire netting used as al reinforcing are secured. lThe several slabs are secured together at their corners by means of plates 10 which are set into horizontal slits 11 punched in the web of the channel frame at each corner. The top flange of the channel, at each corner of the frame has an opening 12 to receive *a pin 13 which passes through a hole in the plate 10, whereby the slabs are securely fastened together. The adjoining corners of the slabs at the end of the floor may also be coupled as herein dethat the slits of adjoining slabs register in i order that the coupling plates may be placed tliereinto. A

- TheV slab hereindescribed is strong and durable and can be easily and cheaply maiiufactured. The outer lsurfaces of the filler are flush with the outer sul-faces of the flanges 6, whereby the slab is given asmooth surface. The flanges 6 extend over the' corners of the filler. which protects the same and prevents the edges thereof from being broken or worn away, and it adds greatly t o the strength of the slab. Any style of reinforcing can be used, and if desired the corner connection of the slabs may be a plate or ring 17 'with a hole 18 large enough in diame-.

ter to receive the four pins as shown in Fig. 5. These slabs can be made of any size or shape desired, and after the concrete has 'become seasoned', they may beshipped to .the building site, and placed in position for iiniiiediate use, regardless of the state of the weather and without delayin travel/,if used for bridge fiooring. The sla s can also 'be used in the construction of floors in buildings,
